I am looking at doing bio and when I was in the local chinese food place the chef said they use vegitable shortening. He said a company already came by to get it for free and they did not want it. He is paying to have it taken away and I would bet if I could use it he would give it to me no problem. So can I use this stuff. I am going to do a SVO setup first to the truck. Do I need to get a bio-diesel setup to refine this stuff? Free is GOOD. /ubbthreads/images/graemlins/biggrin.gif
